* Enforce definition of `DIODE_DIRECTION` for non-custom matrix boards
* Define diode direction for failing boards
* Matching parentheses
* Put onekey diode directions in top level config
* Remove keymap_config extern from default keymaps
* Revert unicode
Apparently VSCode does not like unicode, I didn't actually edit these lines, so it must have been automatic... :(
